Sluggish joypad response
-
@markyh444 My TV doesn't have any such modes.
-
@SpudsMcToole Fair enough.
-
Any tv with hdmi input should have a gaming mode somewhere in the picture settings (there are usually a bunch to choose from like sports/movie/vivid/etc...). If you have a tv that doesn't allow you to change this setting, then try a different tv and see if you still have the lag after switching to game mode. When I first started using emulators, I spent hrs trying to figure out why I had so much lag and it was because I wasn't in game mode. If we can rule this out, then I have some other suggestions that could help with the lag you are experiencing.
-
I can second about checking for turning on your "Game Mode" if your TV has that option. Most modern flat screens do. If you don't there is something else you can try.
When playing ps1 games I did notice lag compared to other systems. I opened up the retroarch settings in-game (default hotkey is set to "SELECT + X" I believe). From there go into Settings, then Input. Try changing the INPUT POLL settings to early or late and see if that helps. Setting mine to Late helped with my controller.

Additionally, you should connect directly from the Pi to the TV and not through sound bars, AV receivers etc. I was trying to isolate the source of some latency and then it dawned on me that my Pi was being routed through my Harman Kardon receiver. Well, the receiver was doing some post processing (resolution checks and audio mode filtering) and it was introducing just a few milliseconds of lag that I could feel more than see. I changed the HDMI mode to passthrough on the receiver and all is well.
If you have that much latency, something in your setup, not the Pi, is adding it.
-
@batesman The Pi is plugged straight into the HDMI port of the TV.
-
@SpudsMcToole what type of TV is it? How old? What model? Most TV's even pretty basic LCDs have a few different picture modes including Game/PC. I find it odd that yours lack this feature.

It is odd. I always shop for televisions that omit these features outright and it becomes more and more difficult all the time.

@mediamogul my 15" magnavox "appletv iie" (as i like to call it) doesnt not have any of these kinds of options. It lacks a lot of options. However it does have pip, which without a remote took me about an hour to figure out how to get rid of. But it does have a physical power switch which was perfect for putting in an apple ii monitor case.
-
Nice! Was the power switch accessible through the case automatically, or did you reroute it?
-
@mediamogul im not exactly sure what you are asking. i rewired it to the apple monitors power button on the top right side of the front of the apple monitor case. ive made two of these. this might mean im the first person to mass produce apple tv's. :)
-
That looks really nice! The monitor is a perfect fit.
-
@Jahnadrian Turns out it was set to Late by default, but I couldn't detect any appreciable difference when I tried switching it to Normal or Early :(
-
@columboscoat Samsung 55" Smart 3D, about five years old.
-
@SpudsMcToole I'm even more sceptical that your TV does not have different picture modes. The settings are on there. Have you looked a bit deeper. This might help... https://displaylag.com/how-to-enable-game-mode-on-your-hdtv/
-
@SpudsMcToole can you give us the model number? I am about 99% positive it is on there. May not be in video setting.
-
@columboscoat It has picture modes, but nothing relating to gaming. I've got Dynamic, Standard, Movie and Natural. None of them affected joypad response.
-
@SpudsMcToole looks like for certain Samsung tvs, game mode is in a separate area from picture mode. Check this out and see if this helps. At this point, I'm feeling pretty confident that not being in game mode is the culprit of your lag issue.
It is very confusing why Samsung would make it so difficult to find game mode, typically it is just in display settings for most tvs. For Samsung, it will be under system/setup.
-
@actnash I was just about to link that second video! Odd that it's not with the other picture modes but every manufacturer is different.
-
@actnash Ah, yes, I have that menu. Never even thought of looking separately from the other picture options, cheers. Have set Game Mode but I'm not seeing much difference to joypad response, if any. (Palette and sound have changed.)
